“Vikings: the North Atlantic Saga” explores the little-known story of the dramatic Viking/Norse expansion across the North Atlantic between 850 and 1000 AD, and their explorations and settlement in Greenland and Northeastern North America. Special emphasis is on fads and fallacies in popular beliefs about “Vikings” in North America as contrasted with new archaeological evidence from Arctic and Subarctic regions where Norse contacts occurred with Native Americans — both Inuit and Indian. Finally, the lecture addresses the likely causes of failure of the western Norse colonies and implications for future human Arctic endeavours.
